         THIS FIRST AMENDMENT (this "Amendment") dated as of January 9, 2004 and
effective in accordance with Section 4 below, is entered into by and among ARMOR
HOLDINGS, INC., as Borrower (the "Borrower"), the lenders from time to time
party to the Credit Agreement referred to below (the "Lenders"), BANK OF
AMERICA, N.A., as Administrative Agent (the "Administrative Agent"), WACHOVIA
BANK, NATIONAL ASSOCIATION, as Syndication Agent, and KEYBANK NATIONAL
ASSOCIATION, as Documentation Agent.

                              STATEMENT OF PURPOSE

         Pursuant to the Credit Agreement dated as of August 12, 2003 (as
amended, restated, supplemented or otherwise modified, the "Credit Agreement")
by and among the Borrower, the Lenders, the Administrative Agent, the
Syndication Agent and the Documentation Agent, the Lenders have agreed to make,
and have made, certain extensions of credit to the Borrower.

         The Borrower has requested that the Required Lenders amend the Credit
Agreement as provided herein and, subject to the terms and conditions set forth
herein, the Required Lenders are willing to consent to such amendment.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties hereto, such parties
hereby agree as follows:

         SECTION 1. DEFINITIONS. All capitalized terms used and not defined
herein shall have the meanings assigned thereto in the Credit Agreement.

         SECTION 2. AMENDMENTS.

                  (a) Section 7.11 of the Credit Agreement (Limitation on
         Investments, Loans and Advances) is hereby amended by amending and
         restating clause (j) of such Section in its entirety as follows:

                           "(j) investments in the form of open-market purchases
                  of publicly traded securities made for the ultimate purpose of
                  consummating or preparing to consummate Permitted Acquisitions
                  ("Market Purchases") in an aggregate amount for all such
                  Market Purchases not to exceed $20,000,000 at any time while
                  such Permitted Acquisitions are pending or contemplated and
                  not yet consummated. Notwithstanding the foregoing, however,
                  the Borrower may make additional Market Purchases in excess of
                  the $20,000,000 limitation set forth above; provided that (i)
                  the ratio of Consolidated Senior Indebtedness to Consolidated
                  EBITDA as of the last day of the most recent Rolling Period
                  (calculated on a pro forma basis as if such Market Purchase,
                  and the incurrence of any Indebtedness by any Loan Party in
                  connection therewith, had occurred immediately prior to such
                  day) is less than 1.0 to 1.0 and (ii) in no event shall the
                  aggregate amount for all



                  Market Purchases made pursuant to this clause (j) exceed
                  $50,000,000 at any time while such Permitted Acquisitions are
                  pending or contemplated. Subject to the limits set forth
                  above, the Borrower and its Subsidiaries may retain
                  investments from Market Purchases regardless of whether the
                  related Permitted Acquisition is consummated; and"

                  (b) Section 7.18 of the Credit Agreement (Governing Documents)
         is hereby amended and restated in its entirety as follows:

                  "7.18 GOVERNING DOCUMENTS. Amend, modify or change its
                  articles of incorporation (or corporate charter or other
                  similar organizational documents) or amend, modify or change
                  its bylaws (or other similar documents) in any manner adverse
                  in any respect to the rights or interests of the Lenders."

         SECTION 3. CONSENT. Solely for purposes of calculating (a) the ratio of
Consolidated Total Indebtedness to Consolidated EBITDA and (b) the ratio of
Consolidated Senior Indebtedness to Consolidated EBITDA for the Rolling Period
ended December 31, 2003, the Borrower shall be permitted to exclude the
outstanding Indebtedness under the 8% senior subordinated convertible notes of
Simula, Inc. from Consolidated Total Indebtedness and Consolidated Senior
Indebtedness.

         SECTION 4. EFFECTIVENESS. This Amendment shall become effective on the
date that (a) the Administrative Agent shall have received satisfactory evidence
that this Amendment has been duly executed and delivered by the Borrower, the
Guarantors and the Required Lenders; (b) the Administrative Agent shall have
received any other documents relating hereto that shall be reasonably requested
by the Required Lenders or the Administrative Agent prior to the date hereof;
and (c) the Administrative Agent shall have been reimbursed for all legal fees
then due and payable by the Borrower and invoiced prior to the date hereof.

         SECTION 5. LIMITED EFFECT. Except as expressly provided in this
Amendment, the Credit Agreement and each other Loan Document shall continue to
be, and shall remain, in full force and effect and this Amendment shall not be
deemed or otherwise construed (a) to be a waiver of, or consent to or a
modification or amendment of, any other term or condition of the Credit
Agreement or any other Loan Document, (b) to prejudice any other right or
remedies that the Administrative Agent or the Lenders, or any of them, may now
have or may have in the future under or in connection with the Credit Agreement
or the Loan Documents, as such documents may be amended, restated or otherwise
modified from time to time, (c) to be a commitment or any other undertaking or
expression of any willingness to engage in any further discussion with the
Borrower or any other person, firm or corporation with respect to any waiver,
amendment, modification or any other change to the Credit Agreement or the Loan
Documents or any rights or remedies arising in favor of the Lenders or the
Administrative Agent, or any of them, under or with respect to any such
documents or (d) to be a waiver of, or consent to or a modification or amendment
of, any other term or condition of any other agreement by and among the
Borrower, on the one hand, and the Administrative Agent or any other Lender, on
the other hand. References in the Credit Agreement

                                       2

hereof, and after giving effect to this Amendment, the Borrower hereby certifies
that (a) each of the representations and warranties set forth in the Credit
Agreement and the other Loan Documents is true and correct in all material
respects as of the date hereof as if fully set forth herein (other than

Credit Agreement, which representations and warranties shall have been true and
correct as of such specific dates) and that as of the date hereof no Default or
Event of Default has occurred and is continuing, and (b) the execution, delivery
and performance of this Amendment have been authorized by all requisite
corporate action on the part of the Borrower and the Guarantors.

         SECTION 7. EXPENSES. The Borrower shall pay all reasonable
out-of-pocket expenses of the Administrative Agent in connection with the
preparation, execution and delivery of this Amendment, including, without
limitation, the reasonable fees and disbursements of counsel for the
